First thin slice of the offline library-improvement proposer. DEV-TIME ONLY,
propose-only — it never mutates the pattern library or the runtime.
- FindDedupCandidates (proposer_dedup.go): structural near-duplicate detection
over the fired patterns (category + measure/zone/scenario overlap). Bakes in
the P1 lesson: only same-category pairs compare, and pairs with different
operational states are never proposed (normal-operation vs maintenance are
legitimately distinct, e.g. HP011 vs HP077).
- ScreenSupersession (proposer_screen.go): the wall. A proposal is safe only if
(1) dropping the hazard does not reduce GT recall AND (2) keep/drop do not
credit DIFFERENT GT entries. Check 2 catches distinct hazards that merely share
measures (HP2201 hot surface GT 1.3 vs HP2202 hot ware GT 1.4) which recall
alone would wave through.
On real warewashing output: 3 candidates -> 1 BLOCKED (distinct GT), 2
RECALL-SAFE for human/LLM review (the update + winding/friction near-dupes).
Nothing auto-applied. All 3 GTs unaffected (read-only). The LLM judgement and a
CLI/file queue are slice 2.
